GUADALAJARA, Mexico  The historic seizure of 15 tons of pure methamphetamine in western Mexico, equal to half of all meth seizures worldwide in 2009, feeds growing speculation that the country could become a world platform for meth production, not just a supplier to the United States.

The sheer size of the bust announced late Wednesday in Jalisco state suggests involvement of the powerful Sinaloa cartel, a major international trafficker of cocaine and marijuana that has moved into meth production and manufacturing on an industrial scale.

Army officials didn't say what drug gangs could have been behind the dozens of blue barrels filled with powdered meth. Army Gen. Gilberto Hernandez Andreu said the meth was ready for packaging. There was no information on where the drugs were headed.

Jalisco has long been considered the hub of the Sinaloa cartel's meth production and trafficking. Meanwhile, meth use is growing in the United States, already the world's biggest market for illicit drugs.

The haul could have supplied 13 million doses worth over $4 billion on U.S. streets.

The Sinaloa cartel, headed by Joaquin "El Chapo" Guzman, is equipped to produce and distribute drugs "for the global village," said Antonio Mazzitelli, the regional representative of the U.N. Office on Drugs and Crime.

"Such large-scale production could suggest an expansion ... into Latin American and Asian markets," Mazzitelli said. But he also noted, "it may be a product that hasn't been able to be sold, and like any business, when the market is depressed, stockpiles build up."

A senior U.S. law enforcement official in Mexico said the operation raided in Jalisco was "probably Sinaloa."

The official, who could not be quoted by name for security reasons, said Sinaloa may be trying "to reduce its reliance on Colombian cocaine by flooding the market with meth."

Reporters were shown barrels of white and yellow powder that filled three rooms on a small ranch outside Guadalajara, Mexico's second-largest city.

The lot around the house, which included an empty swimming pool, was littered with metal canisters and cauldrons used in the production process. While the equipment appeared makeshift and partially dismantled during a tour of the facility given to news media, it was apparently used intensively.

There were no people found on the ranch or arrests made, although it appeared 12 to 15 people worked there.

The seizure of such a large quantity of meth is expected to have a big impact on the U.S. meth market. A pound of meth can sell for about $15,000.

"This could potentially put a huge dent in the supply chain in the U.S," said U.S. Drug Enforcement Administration spokesman Rusty Payne. "When we're taking this much out of the supply chain, it's a huge deal."

But that may not ultimately mean less meth in the U.S. Law enforcement officials in California's Central Valley, a hub of the U.S. methamphetamine distribution network, say a cutoff in the Mexican supply could mean domestic super labs will increase production.

"This will be a big seizure and will most likely slow down distribution for a short period of time until manufacturing can continue," said Robert Penal, a meth expert and former commander of California's Fresno Methamphetamine Task Force. "However, when there is an interruption in supply it is not uncommon for domestic super labs in California to start up operations to fill the void until the supply from Mexico can be restored."
